Ruby 3.3 Compatibility

[cloke]

After upgrading to ruby 3.3.1 from 3.2.2 the interfax gem fails with the following error:

/versions/3.3.1/lib/ruby/gems/3.3.0/gems/interfax-1.2.1/lib/interfax/object.rb:1:in `<main>': uninitialized constant OpenStruct (NameError)

Adding require "ostruct" to object.rb resolves the issue.

Curious if this gem is maintained? Have a PR from a year ago to address a small ruby update that would love to see get merged.
